The component of atom discovered by Rutherford is protons.
According to his gold foil experiment, where he bombarded alpha-particles on gold foil he discovered a positive charge center in the atom. The concentrated center has most of the mass of the atom. The positive center was introduced as nucleus containing positive charged particles, protons.
The statement that best describes an advantage of cloning is that it can prevent genetic diseases. DNA cloning is a term used in recombinant DNA technology happens when a DNA strand belonging to one organism is transmitted into a particular type of genetic element having the capacity to self replicate. DNA cloning was developed to offer solutions related to healthcare and medical issues. Illnesses occur mostly because our body fails to produce essential proteins in ample amount is needed, these problems and other inherited problems may be solved using DNA cloning.
Releasing the string would most likely increase the kinetic energy, as kinetic energy is energy in motion. However, if you were to increase the potential energy, then the string would have to be pulled back more, as potential energy is stored energy within an object.
Answer:
Q = 7898.38 J = 7.898 KJ
Explanation:
∴ ΔHv H2O = 47 KJ/mol = 47000 J/mol
∴ molar mass H2O = 18.015 g/mol
⇒ ΔHv H2O = (47000 J/mol)*(mol/18.015 g) = 2608.94 J/g
∴ m H2O = 2.73 g
⇒ ΔHv H2O = (2.73 g)(2608.94 J/g) = 7122.406 J
∴ C H2O = 4.18 J/g°C
∴ ΔT = 100 - 32 = 68°C
⇒ Q = (2.73 g)(4.18 J/g°C)(68°C) + 7122.406 J
⇒ Q = 775.975 J + 7122.406 J
⇒ Q = 7898.38 J
